Agronomic Tools

Empowering your fertility decisions.

Every tool here turns agronomy into one clear number: what works, what it pays, and how it fits your operation. Start with the two below, then dig into the specialty tools.

Looking for the Phosphate ROI, Sulphur, Potash or $/lb of Nutrient tools? Their jobs are now done by the Price Impact Calculator, which compares any two products on the same footing — pick your products and nutrient there.

Phosphate, Perfected.
Phosphate ROI Calculator

How much do you want to spend per acre on phosphate?

Start with your spend. Add real prices. See which product puts the most plant-available phosphorus in front of the crop for the same dollars.

Set your spend to see your numbers

Enter your phosphate spend per acre, your current product price and your Crystal Green quote — Canadian dollars per tonne. Everything else is pre-filled and fully editable.

The Bottom Line

Set your spend above.

Phosphate, Perfected.
Assumptions and how the math works
Rate applied = spend ÷ price per tonne × 2,204.62 lb (or 1,000 kg in metric). Total P₂O₅ = rate × P₂O₅ %. Plant-available P = total P₂O₅ × plant-available %. Cost per lb usable P = spend ÷ plant-available P. “To match” is the per-acre spend your current product would need to deliver the same usable P as the selected Crystal Green product. All prices are Canadian dollars per metric tonne (MT). These figures are planning estimates for comparison, not an agronomic recommendation or a yield guarantee. Confirm rates and placement with your agronomist and soil tests. CG P2X from Ostara.

How much phosphate are you actually paying for?

Conventional P spends most of its phosphorus tying up in the soil before your crop can use it. Enter your numbers to see the one figure that matters: cost per pound of plant-available phosphorus.

The Bottom Line

Run your numbers above.

Phosphate, Perfected.
Assumptions and how the math works
Plant-available P per acre = rate × P₂O₅ % × plant-available %. Cost per acre = rate (lb/ac) × price ($/MT) ÷ 2,204.62 lb per tonne. Cost per lb usable P = cost per acre ÷ plant-available P per acre. "Cost to match" scales your current product up to the rate needed to deliver the same usable P that the selected Crystal Green product provides.

What you'd actually have to apply

03

A pound removed is not a pound applied. Only part of what goes on reaches this year's crop; the rest is tied up, lost, or feeds later seasons. Pick the source you use for each nutrient and the year-1 efficiency fills in. The tool then shows how much nutrient, and how much product, it takes to put back what this crop removes.

Year-1 efficiency values are Taurus estimates from the Program Builder reference table, unadjusted for field conditions here; edit any value to match your own experience. For a two-product comparison on your price, use the Price Impact Calculator.

Sulphur ROI

Sulphur Rate & Value Calculator

Most sulphur tools just give you a rate. This one shows how much sulphur the plant can actually use this season, and what each product is really worth once you count the nutrients riding along with it.

Prices are regional and move fast — drop in your own ($ per tonne). Defaults are placeholders so the tool runs on load.
Advanced — analysis, availability & nutrient credits

Defaults are typical guaranteed analyses — verify against current product labels before publishing. "First-season available S" is the share of total S the crop can take up this year: sulphate is ready now, elemental sulphur must oxidize first.

These value the riding-along nutrients at what you’d pay for them anyway. Defaults: N from urea at $800/tonne, P₂O₅ from MAP at $1,500/tonne (net of its N), fulvic acid at $1.50/lb. Set any to 0 to ignore.

Full value: Taurus vs. conventional
Sticker price lies when a product carries more than sulphur. True S cost credits the other nutrients at replacement prices (MAP, urea, potash) — that’s the honest number to compare, all at your S target.

Why it matters
    Salt index and biology-impact ratings reflect general characteristics of each fertilizer type (ammoniated vs. sulphate vs. elemental forms) — confirm current product-specific lab data before publishing externally.
    How the math works

    First-season available S (lb/ac) = product rate × Total S% × Avail S% (yr 1).

    Rate needed (lb product/ac) = your S target ÷ (Total S% × Avail S% (yr 1)).

    $ / ac = rate ÷ 2,204.62 lb per tonne × price per tonne.

    $ / lb available S = $/ac ÷ your S target.

    Nutrient credit ($/ac) = (lb Ca × $/lb Ca) + (lb K₂O × $/lb K₂O) + (lb Mg × $/lb Mg) + (lb N × $/lb N) + (lb P₂O₅ × $/lb P₂O₅) + (lb fulvic acid × $/lb fulvic), valuing each riding-along input at its replacement price — what you’d pay for the same pounds as urea, MAP or potash.

    Net $ / ac = $/ac − nutrient credit. That's what the chart stacks: net cost on the bottom, credit value on top — together they always add back up to the sticker $/ac.

    Budget mode flips it around: Rate (lb product/ac) = budget ÷ price × 2,204.62. Available S delivered = rate × Total S% × Avail S% (yr 1). We plot that against your crop’s target so a flat budget’s real payoff shows up at a glance.

    Compare across crops
    Same product, different crop demand — pick two or more to see the $/ac spread.

    Spring wheat (10 lb/ac)
    Barley (10 lb/ac)
    Alfalfa / hay (25 lb/ac)
    Corn (15 lb/ac)
    Soybean (12 lb/ac)
    Field peas / lentils (8 lb/ac)
    Why it matters

    Cheapest per pound isn't cheapest per pound the plant can use.

    Potash ROI

    Potash Rate & Value Calculator

    Hitting a K₂O target is the easy part. The real question is what comes attached to it — how much salt sits next to the seed, how much chloride you're hauling, and which nutrients ride along for free. This tool puts those side by side.
